Purpose: The purpose of this study was to determine the quantity of Streptococcus mutans serotype c and Candida albicans antigens from dental plaque and their relationship with the Oral Hygiene Index Score (OHI-S) and Decayed, Missing, and Filled Teeth (DMFT) in Early Childhood Caries (ECC) and Severe Early Childhood Caries (S-ECC). Materials and Methods: This was a cross-sectional study, including 5 ECC and 32 S-ECC subjects. ECC was classified as a DMFT score < 4, and S-ECC was classified as a DMFT score ≥ 4 at 71 months of age. S. mutans serotype c and C. albicans antigens from dental plaque of ECC and S-ECC patients were measured using enzyme-linked immunosorbent assays. The optical density of S. mutans serotype c and C. albicans antigens was determined at 450 nm. Correlations between S. mutans serotype c and C. albicans antigens and OHI-S in ECC and S-ECC were analyzed. Results: There were no significant differences in S. mutans serotype c and C. albicans antigens between ECC and S-ECC patients or between patients with moderate and good OHI-S scores. There was a negative correlation between S. mutans serotype c and C. albicans antigens in ECC patients (r =-0,62; p < 0.05). Conclusion: The increase in C. albicans suppresses S. mutans serotype c growth in ECC but not in S-ECC. The findings of this study could be used to discover the molecular mechanisms involved in bacterial-fungal relationships and the contribution of new technologies to reduce ECC.
